While the Dodge Viper is on hiatus—the next-gen snake will arrive in late 2012—a version of its engine has been added to the fall schedule: Mopar announced at the SEMA show that it will offer a ready-to-race drag version of the iconic V-10. Pushing an extremely healthy 800 hp and 695 lb-ft of torque from 512 cubic inches, the crate motor has a 7000-rpm redline and a 12.5:1 compression ratio. As you’d expect, the block and heads are aluminum. It also boasts forged internals, including the aluminum pistons and steel crankshaft and connecting rods, and the ECU has been specially calibrated for quarter-mile use. Chrysler says road-race and off-road versions are coming, too.

Owners of third-gen Vipers also got good news, as a bolt-on Performance Upgrade Kit was announced for those cars’ stock V-10s. It combines new aluminum heads, a new upper intake manifold with enlarged throttle body, and new fuel rails to boost output by 150 hp. Good thing, we say, because we’d have become bored with our third-gen Viper’s paltry 500 horses years ago.
